Abstract
The gain-saturated semiconductor-laser-amplifier (SLA) wavelength converter (WC) operates by the presence (absence) of a modulated optical input signal reducing (increasing) the gain experienced by a cw optical pump at a different wavelength.1 In a wavelength-division-multiplexed (WDM) network, a signal might pass through several WCs during its passage. To our knowledge, this is the first study of cascading this type of WC.
